Forms

Academic Agreement forms are required to use some third-party software. These documents apply to more than one platform or to no particular platform. A complete list is available on the forms page.

Charging

The following text describes the charging algorithms for academic use on OSC hardware.

Charging for Academic Use

Supercomputer resources on The Cluster are charged in terms of Resource Units, a common measure of the use of CPU and file storage across all platforms.

The charging formula for RUs consumed by a process is:RU = 0.1 × Tt
where RU is the charge in Resource Units for the process being considered and Tt is the total CPU time in hours for all CPUs.

The formula for calculating total CPU time differs between parallel and serial jobs. Parallel jobs are charged for whole nodes regardless of the ppn request submitted. This means if you were to only request ppn=2 for a 2 node parallel job on Oakley, you would be charged as if you requested a ppn=12 regardless.

There is no charge specifically for GPU usage. There is a difference in how GPU jobs are allocated normal processors, and therefore charged, between Oakley and Glenn. Serial GPU jobs on Oakley may request partial nodes ( ppn < 12 ) and will only be allocated their requested processors like a normal serial job, while on Glenn serial GPU jobs are allocated like parallel jobs ( they must request the whole node via ppn=8 ) and therefore are charged like them.

Statewide Software Library

The Ohio Supercomputer Center manages a program that offers state-of-the art software installed at the user's home site. Originally this program was titled "Statewide Software Library." That is subsumed by the later program: Statewide Software Distribution.
